Answers
Answer:
1. The negative flips the parabola upside down so there is a maximum
2. The 1/2 means there is a vertical shrink
3. -3 means the graph moves to the RIGHT 3 units (X sign always changes)
4. +12 means the graph shifts up 12 units
Step-by-step explanation:
g(x)=x^2 is the parent function. This is the most basic parabola, and transformations are added to alter the function’s lateral and vertical location and width or length.
Now that we have the parent function, let’s address the transformations done to it. Remember, when identifying transformations, remover to follow PEMDAS; act like you are inputting a value in for x and following PEMDAS to observe how the function is altered.
• Lateral shift 3 units to the right
*Remember, horizontal translations have opposite signs, so even though x is subtracted by 3, it will actually move to the right towards the positive direction.
•Reflect over the x-axis
•Shrink by a factor of 1/2
*This will produce a wide parabola
• Vertical shift up 12 units

The vertices of ▲ XYZ are X (6,-5), Y (3,0), Z (-4, 9). A XYZ is translated 3 units left and 8 units up. Then, it is translated 2 units right and 6 units down. What is the final translation rule that maps the pre-image to the final image?
Answers
Answer:
After the first translation, the coordinates of the vertices of the triangle will be X (3,-13), Y (0,-8), Z (-7, 1). After the second translation, the coordinates of the vertices will be X (5,-7), Y (2,-2), Z (-5, 7).
The final translation rule that maps the pre-image to the final image is a translation of 2 units right and 6 units up. This can be written as a translation rule of the form (x, y) -> (x + 2, y + 6).
Step-by-step explanation:
After the first translation the coordinates are:
(x, y) → (x - 3, y + 8)After the second translation the coordinates are:
(x - 3, y + 8) → (x - 3 + 2, y + 8 - 6) = (x - 1, y + 2)The final translation rule is:
(x, y ) → (x - 1, y + 2)or

Answer:
D
Step-by-step explanation:
it is a regular pentagon.
so, all side lengths are equal, and also all cross connections between corners are equal.
that makes TR parallel to PQ.
and that makes SPQ an isoceles triangle (both legs are equally long). and the smaller triangle S to x to the angle to the right of x is similar to SPQ, which means they have the same angles.
so, the triangle interior angle at P = the triangle interior angle Q = y.
and they must be the same as the bottom 2 interior angles of the small triangle.
x and the angle right to x are equal too, as they are the triangle exterior (supplementary) angles to the bottom 2 interior angles of the small triangle.
we know that the sum of all angles of the internal trapezoid (PQ to x and its right neighbor) is 360.
and based on the EqualLogic found above these angles are
2×x + 2×y = 360°
x + y = 180°

What is Coordinate Geometry?The study of geometry using coordinate points is known as coordinate geometry (also known as analytical geometry). Finding the distance between two points, breaking lines into m:n segments, locating a line's midpoint, computing a triangle's area in the Cartesian plane, and other operations are all feasible using coordinate geometry.
A straight line is represented using its slope and a point on the line using point slope form. This indicates that the point slope form is used to get the equation of a line whose slope is "m" and which passes through the points (x 1, y 1). The equation of a straight line can be expressed in several ways. Point slope shape is one of them. Y - Y 1 = m(x - X 1) is the equation for the point slope form, where (x1, y1) is a randomly chosen point on the line and m is the slope of the line.
The slope of the line is 1.5
The Point through which the equation will satisfy is (6,12)
Therefore the equation of the line in Point-Slope form is
y - y1 = m ( x- x1)
⇒ y - 12 = 1.50 ( x - 6)
Option D, The equation that satisfy the situation is y - 12 = 1.50(x-6).

Mary has 96 fliers to post around town. last week she posted 1/6 of them. this week she posted 1/4 of the remaining fliers. How many fliers has she still not posted?
Answers
Answer:
Start with 60 fliers
post 1/4 of fliers so 60*.25=15
60-15=45 left
post 1/5 of remaining so 45*.20=9
45-9=36 left
Step-by-step explanation:
Last week: (had 60) (used 1/4)= (60)(1/4)= 15. So, you used 15.
You have 60-15=45 left. This is how many you have to start the week.
This week: (had 45) (used 1/5)= (45)(1/5)= 45/5=9. So, you used 9.
This means that you have 45-9= 36 left.
Mary Still did not post 60 fliers.
Total fliers Mary was having = 96
Fliers she posted last week = 1/6 = 0.16
Fliers left with Mary after posting 1/6 part last week
= 96 x 0.16
= 16
Fliers left with Mary after the posting of 1/6 of them
= 96 - 16
= 80
Now the new remaining number of fliers with Mary = 80
Fliers she posted this week = 1/4 = 0.25
Fliers left with Mary after posting 1/4 part this week
= 80 x 0.25
= 20
Fliers left with Mary after the posting of 1/4 of them this week
= 80 - 20
= 60
Therefore, the fliers that Mary still did not post = 60

Answers
The rate of increase in stock price is $ 0.10 per hour.
Calculating the Rate of increase:To calculate the rate of increase we need to know the increased amount per given time period
In this problem, we will calculate the stock price per given hour from that will calculate the rate of increase in a given situation.
Here we have
The price (in dollars) of a stock tracked from noon to three on a given day is shown by the function f(t) = 0.1(t - 2)³ + 6 where t is in hours.
Take t = 1
=> f(1) = 0.1(1 - 2)³ + 6
= 0.1(-1)³ + 6
= 0.1(-1) + 6
= - 0.1 + 6
= 5.9
Take t = 2
=> f(2) = 0.1(2 - 2)³ + 6
= 0.1(0)³ + 6
= 6
Take t = 3
=> f(3) = 0.1(3 - 2)³ + 6
= 0.1(1)³ + 6
= 0.1 + 6
= 6.1
The rate rate of increase = f(3) - f(2) = 6.1 - 6 = 0.1 ≅ $ 0.10

Answers
Therefore, the linear speed of the wheel on a bike is approximately 0.9π miles per hour.
What is meant by linear speed?The pace at which an object travels a specific distance in a predetermined amount of time is known as linear speed. By dividing the distance traveled by the time it takes to cover that distance, it may be used to determine how rapidly an item is travelling in a straight line. For instance, if a car moves 100 meters in 10 seconds, its linear speed is 10 meters per second. Linear speed is distinct from average speed, which takes into account any variations in velocity or direction throughout the duration of a voyage. Linear speed is also distinct from tangential speed, which is the pace at which an item travels along a circular route. Physics' fundamental idea of linear speed.
How to solve?
C=2πr,
C=2π(19)=38π.
linear speed of v=(38π/60)*5280=33.6π feet per second.

Answers
Considering the climate of the North Pole, Alaska, we have seen that the change in the Temperature is 13°F and 14 °F respectively on the 1st and last day of the month respectively.
How to calculate the change in temperature?
From records, we know that Alaska usually has an average low temperature of 9°F and an average high temperature of 22°F in January.
However In February, Alaska's temperature usually ranges from an average low temperature of 12°F to an average high temperature of 26°F.
Thus, we can find the change in Temperature:
On 1st day of January , the Change in temperature is;
ΔT = Highest Temperature - lowest temperature
ΔT = 22°F - 9°F
ΔT = 13°F
On the 1st day of February, and then the last day of January, the change in temperature is;
ΔT= Highest Temperature - lowest temperature
ΔT = 26°F - 12°F
ΔT = 14 °F.
The hardest part will be to take take care of the animals since most of the animals only require a warm, secure, as well as protected area to reside in addition to sufficient food, drink, and exercise.

The profit a company made decreased 20% to 66 million from one year to the next. What was the profit the year before
Answers
82.5 million was the profit the year before the profit decreased 20% to 66 million from one year to the next
What does profit means ?
Profit is the term used to describe the financial gain experienced when the revenue from a commercial activity exceeds the costs, costs, and taxes associated with maintaining that activity.
Any profits generated are returned to the company's owners, who can decide whether to keep the money for themselves, pay dividends to shareholders, or reinvest it in the company.
Entire revenue less total costs equals profit.
Companies report gross profit, operational profit, and net profit for accounting purposes (the "bottom line").
Investors are drawn to profitable businesses because these businesses either distribute their earnings as dividends to shareholders or invest them back into the business, which raises stock value.
According to the question Company lost 20% from its profit and it reached to 66 million that means
let X be the total profit of the year
X - loss percent = 66 millions
X - X (20/100) = 66 million
X-0.2X = 66 million
0.8X = 66 million
X= 66/0.8 million
